Description

Contemporary design methods of bearing capacity of deep foundation (pile foundation) change according to different design codes. The main requisition of the designing process of the deep foundation is related with the axial bearing capacity, which should be sufficient to withstand the applied loads. Many authors has developed and published detailed methods to analyze the behavior of a single reinforced concrete pile or a group of piles, based on vertical bearing capacity due to lateral friction or residence at the pile point. The goal of this paper is to illustrate the calculation methods according to 3 analytical methods of vertical bearing capacity of bored single pile and group of piles of a bridge foundation. Only the vertical loads are considered during the design process. Shear loads and bending moment act as horizontal loads on the group of piles. A comparison between three different methods is shown to determine the bearing capacity and the stress limit allowed. The bridge is located in the 26 kilometer of Elbasan-Tiranë highway.

Contemporary design methods of bearing capacity of deep foundation (pile foundation) change according to different design codes. The main requisition of the designing process of the deep foundation is related with the axial bearing capacity, which should be sufficient to withstand the applied loads. Many authors has developed and published detailed methods to analyze the behavior of a single reinforced concrete pile or a group of piles, based on vertical bearing capacity due to lateral friction or residence at the pile point. The goal of this paper is to illustrate the calculation methods according to 3 analytical methods of vertical bearing capacity of bored single pile and group of piles of a bridge foundation. Only the vertical loads are considered during the design process. Shear loads and bending moment act as horizontal loads on the group of piles. A comparison between three different methods is shown to determine the bearing capacity and the stress limit allowed. The bridge is located in the 26 kilometer of Elbasan-Tiranë highway.
